Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172038, here are decompositions:

7 + 172031 = 172038
11 + 172027 = 172038
17 + 172021 = 172038
29 + 172009 = 172038
37 + 172001 = 172038
101 + 171937 = 172038
109 + 171929 = 172038
149 + 171889 = 172038

Showing the first eight; more decompositions exist.
